  • Is the best PCB etchant in every kitchen ?

    You can buy up to 12% in the EU and anything over that is restricted. I purchased 30% a while back but when I returned for more I found that only up to 12% was available to the general population in the UK. I now get 9% so I do not have to mess around watering down with distilled water.

    How to make COLLOIDAL SILVER  (Easy)

    Before you consider using this internally, do yourself a favour and leave the saline out! It will take longer as a result because the water resistance is higher. Using some from a previous batch would help speed up the process.Then you should get a current regulating diode of 1mA. This needs to be hooked into the positive lead after the batteries and before the electrode. This will ensure that the current does not rise when the resistance lowers as more silver ions enter the water. This is very important! This will keep the quality high and prevent large particles being formed which are harmful. If you look up Papa Smurf the blue man you will see that he used salt in the water and he did not restrict the current flow and he ended up blue/grey as a result.Having something to stir it woul...

If you look up Papa Smurf the blue man you will see that he used salt in the water and he did not restrict the current flow and he ended up blue/grey as a result.Having something to stir it would also be beneficial. You could make a magnetic stirrer from an old PC fan. See youtube for instructions on building one. They can be made fairly cheaply using a lunch box and a fan, two small rare earth magnets/Neodymium which are glued to the fan, preferably a variable resistor and a 12 volt power supply. A stir bar is needed which you put in the bottom of the glass flask. This helps prevent agglomeration of the silver.This does complicate it but it pays to do it safely rather than having regrets because you turned blue/grey.
